Consumer interest group Which? has rated Mosi-guard® Natural ‘best performing’ natural insect repellent in its product comparison tests published this month (July 2012). Which? tested both DEET and DEET-free products from 12 well known brands with results, unsurprisingly, revealing ‘big differences between the most and least effective repellents’. Mosi-guard® Natural earned a maximum five star efficacy rating for providing up to eight hours protection against multiple insect bites which, the report states, ‘ is on a par with our best-performing DEET products’. Mosi-guard® Natural out-performed all non-synthetic products including Jungle Formula Natural, Lifesystems Natural, and Incognito which received the lowest protection rating of all products tested by Which?.
